Aug 13 (Reuters) - German optical electronic group

Jenoptik on Wednesday said it expects its full-year

results to come in at the lower end of its guidance ranges,

citing risks from existing and potential new trade barriers.

The company now expects full-year revenue to be in the lower

half of the forecast range of around 5% higher or lower compared

to the same period last year.

Jenoptik, which partially operates in the semiconductor

equipment industry, also expects its EBITDA margin to reach the

lower half of its forecast range of 18 to 21%.
